JOHN HARTFORD CIIIDESTER, OF DOBBS FERRY, NEW YORK.

SHIPPING-CAN.

Specification of Letters Patent.

Patented July 6, 1909.

Application filed March 18, 1907. Serial No. 362,837.

To all whom it may concern:

Be it known that I, Jonn HARTFORD Cnmnsrnn, a citizen of the United States, residing at Dobbs Ferry, in the county of VVestchester and State of New York, have invented certain new and useful Improvements in Shipmng-Cans, of which the following is a specification, reference being had to the drawing accompanying and forming a part of the same.

This invention relates to metal cans and more particularly to shipping cans.

In the accompanying drawing showing illustrative embodiments of this invention, in which the same reference numerals refer to similar parts in the several figures, Figure 1 is a plan view of my shipping can, a part of the cover being shown broken away to better illustrate the interior of the can and the packing. Fig. 2 is a side elevation of the can, part being broken away. Fig. 3 is a detail showing the preferred means for securing the cover to the can taken on line 33 of Fig. 1. Fig. 4 is a vertical sectional view of a mod'fication taken on a line between adj acent stiffening rods. Fig. 5 is a detail view of a modification in which the inner body is omitted. Fig. 6 is a sectional view of a modified form of cover and packing.

In the illustrative embodiments of this invention shown in the drawing, 1 is a body of the can which may be made of sheet metal or any other suitable material and rolled or stamped to form the longitudinal channels or flutes 2, 2. Within each channel or flute I secure a stiffening rod 3. The bottom of these rods are reduced at 4 forming a shoulder 5, the reduced portion 4 passing through apertures made for them in the bottom plate 6, Fig. 4. This bottom plate is preferably stamped out of a single piece of metal and formed with a longitudinal groove 7 and flange 8 and may if desired, have a stiffening rib 38 of any desired configuration formed therein. Within this annular groove 7 I snugly fit the lower end of the body 1 of the can and also of the inner body 9 when I use two bodies. The upper portion of this bottom plate 6 snugly fits against the shoulder 5 of the rods 3 so as to resist any relative movement between the rod and the bottom plate, the bottom plate being held firmly against the shoulders 5 by the upset ends 11 of the reduced portions 4 of the rods 3. p

The ends of the body portion 1 may be socured together in any suitable manner, such,

for instance, as shown at 12, and when I use the inner body 9 which is preferably made of sheet steel, though other material different from the outer body may be used if desired, I also secure its ends together in any suitable manner, such as shown at 13, arranging the laps or seams of the inner and outer bodies, preferably 180 apart, as shown in Fig. 1. This inner body adds materially to the strength of the can and in that respect supplements the stiffening action of the rods 3, 3, though it is understood, of course, that this inner body may be dispensed with when desired as shown in Fig. 5. The upper portion of these rods 3, 3, are in the preferred form shown in Figs. 1, 2 and 3 flush with the top of the can, each rod being tapped as shown at 14 for the reception of a thumb screw 15, the screw threads 16 of which cooperate with the screw threads of the rods passing through apertures 17 in the cover 18 and apertures 19 in the packing 20, the shoulder 21 of the thumb screw cooperating with the upper surface of the cover in a well known manner to lock the parts together and compress the packing 20, making a hermetically sealed joint. This cover 18 is preferably stamped out of a single piece of metal, preferably sheet metal, and is formed with an annular groove 22 which is enlarged at intervals 23 for the reception of the ends of the bolts 3, 3. To further stiffen the can and also to have an additional bearing surface for the packing I spin or otherwise form an annular rib 24 in the inner body 9 a sufficient distance below the top of the can to form an additional seat 25 for the packing 20 which here cooperates with said additional seat and with the bent portion 26 of the cover 18 to form a supplemental seat. This strengthening rib is so placed as to lessen the pressure of the upper ends of the inner and outer bodies 1 and 9 respectively upon the packing in the grooves 22 which pressure if not lessened would have a tendency to cut or mar the packing. In order to strengthen the upper portion of the can I may also use a separate ring 27, which may be secured to the bodies 1 and 9, respectively, by means of rivets 28. This ring is also located just below the upper end of the can, the upper portion 29 of the ring 27 forming an additional seat for the packin 20, as shown in Fig. 4. As shown in this figure, I may, instead of having the strengthening rods 3, 3 flush with the top of the can, extend them above the rib to form with the body of the can and screw-thread their ends as shown at 30, using in connection with them a hollow screw-threaded thumb screw 31. The sheet packing 20 may be wood, metal, vulcanized flber, rubber or any other suitable material I have shown in Fig. 6 a ring packing 32 which is preferably pressed into and held socurely within the groove 33 of the cover 18 which may of course cooperate with a suitable packing and supplemental strengthening member on the can body, as shown in Figs. 2 and 4.

My can is particularly advantageous for shi ping hermetically heavy merchandise, sucl as meat, lard, or other packing house products, essential oils, chemicals, oXids and liquids, or any other article and is espe- Jially valuable when an air and water tight container is desired which will require no extra crating for shipping, and contents of which can be easily inspected when used, for instance, as in the export trade. For handling the can I use an ordiary handle 34 secured to the body of the can by means of a plate 37 which is preferably secured over the seam 12 of the outer body by means of rivets 36, 36. I may also to further strengthen the can fasten the stiflening rods 3 to the body or to the body and inner body by rivets 35.

The can may be either galvanized, painted or coated with any suitable material.

Having described this invention in connection with several illustrative embodiments thereof, to the details of which I do not desire to be limited, what is claimed as new and what it is desired to secure by Letters Patent is set forth in the appended claims.
